Abstract

A centrifuge bowl for oscillating bowl type rotors with two grooves in opposite sides of the bowl to receive the rotor-bearing pins, so that each groove has a bottom surface and is bound on the side facing the bowl aperture by a curved surface is provided. This achieves higher load change cycles so that higher fields of gravity are possible without the occurrence of the usual material fatigue in the area of the grooves receiving the bearing-pins, that is, of fissuration, because the bottom surface has a cup-shaped indentation which, in the peak area of the curved surface is located ajacent to the latter, and there is at least one slot opening into the indentation in the peak area of the curved surface.
